Non-indicating, current-limiting TPS technology minimizes arc exposure and shields downstream components, reducing maintenance needs and service interruptions in telecom power systems. Business impact: higher equipment availability and lower total cost of ownership through fewer field repairs; application: telecom racks and PCB-mounted power distribution. The TPS-70L features a 100 kAIC interrupt rating at 170 Vdc, delivering robust surge handling to protect DC rails feeding network equipment, data centers, and remote sites. Business impact: improved uptime during fault events; application: DC power distribution in telecom infrastructure. Compact dimensions (0.56 in L, 0.56 in W, 0.88 in H) and a 0.3 lb weight enable dense panel layouts and easy replacement in space-constrained enclosures. Business impact: higher packing density and faster maintenance; application: field-deployable telecom cabinets. Built with glass-melamine tubing and silver-plated brass ferrules, TPS-70L combines rugged construction with CE RoHS compliance for global deployments. Business impact: regulatory certainty and reliable performance across markets; application: standard Bussmann TPS family installations. The PCB-tab feature provides straightforward installation on standard PCBs, reducing assembly time and improving stocking practices. Business impact: lower installation costs and predictable replacement cycles; application: modular telecom power assemblies.
